The present paper discusses design and development of C-V meter which could be interfaced to PC through microcontroller based smart DAC (Data acquisition card). The C-V meter for the measurement of Capacitance between 2pF to 20nF is designed. The circuit also allows measurement of Quality Factor between 101 to 104. The circuit designed here is based on Auto balancing bridge technique. A DC bias voltage of + 10 V is selected in the present case. The results on simulation using MULTISIM 11.0 (version 11.0.1) are also elaborated in the present paper.
